<p>GtkHBox has been deprecated. You can use <a class="link" href="GtkBox.html" title="GtkBox"><span class="type">GtkBox</span></a> instead, which is a very quick and easy change. If you have derived your own classes from GtkHBox, you can simply change the inheritance to derive directly from <a class="link" href="GtkBox.html" title="GtkBox"><span class="type">GtkBox</span></a>. No further changes are needed, since the default value of the <a class="link" href="gtk3-Orientable.html#GtkOrientable--orientation" title="The “orientation” property"><span class="type">“orientation”</span></a> property is <a class="link" href="gtk3-Standard-Enumerations.html#GTK-ORIENTATION-HORIZONTAL:CAPS"><code class="literal">GTK_ORIENTATION_HORIZONTAL</code></a>. If you don’t need first-child or last-child styling, and want your code to be future-proof, the recommendation is to switch to <a class="link" href="GtkGrid.html" title="GtkGrid"><span class="type">GtkGrid</span></a> instead of nested boxes.
